Knowing the blocksize used, I would just tell him to use "mt setblk"
to the same block size, then use "dump" to dump a random ammount
of that to the tape. Dump will provide you with the throughtput rate
you want.
If you don't know the blocksize, or if you are using variable (0),
you really can't measure it outside the specific application you
are using to write the data to the tape.
Seems like it would be easier to just run it through something like
buffer, mbuffer, or dbuffer and have one of those report the value
second by second, in kilobytes per second.
